Further, each half case has a side wall, an end wall, and a top wall.  The end walls of each half case defining an opening through which the arc gasses are vented.  The top walls of each half case define an inverted U-shaped cavity.  A V-shaped screen has one leg thereof placed against the end walls to restrict the opening.  The other leg of the V-shaped screen extends into the U-shaped cavity, but is spaced from the wall defining the U-shaped cavity.  The V-shaped screen has legs which are spaced apart to provide a space through which the arc gasses may pass.  The circuit breaker also includes a stationary contact surrounded on all sides but one by an arc runner which is keyed to a supporting conductor. Further, two or more circuit breaker poles may be interconnected at their handle links with only one handle link extending outwardly of deep wells formed by portions of the half cases for manual operation of the multi-pole circuit breaker formed thereby.

Abstract: ABSTRACT OF THE DISCLOSURE       A pipeline break detection system wherein a rate timer valve is opened in response to a predetermined pressure drop to direct pressure fluid to activate the time cycle of an on delay valve and, itself commence a time delay closing cycle.  If its closing countdown continues to completion, it depressurizes the on-delay output valve and cancels its countdown.  However, if the pipeline experiences a further like pressure drop, before the rate timer valve closes, it will be recharged and held open to keep the output valve timer actuated.          If the pipeline pressure fails to level off to allow the rate timer valve to close, and the output relay is thus enabled to complete its timed cycle, the output relay opens to deliver a fluid signal.

Abstract: DEFROST PRESSURE CONTROL SYSTEM                      ABSTRACT OF THE DISCLOSURE       The defrost pressure control system for a refrigerator includes a reservoir connected in communication with the evap-orator of the refrigerating system.  The reservoir is placed in heat exchange relationship with a portion of the refriger-ator which remains at a relatively low temperature during defrosting so that a portion of the refrigerant in the system condenses in the reservoir during defrosting, thereby being effectively removed from the refrigerating system.  A suitable heat sink may also be employed in the heat exchange relation-ship with the reservoir.  Because of withdrawal of the afore-mentioned refrigerant, the pressure in the refrigerating sys-tem at the end of the defrosting operation is substantially below that which would otherwise be present.  As a result the torque required to start the compressor is significantly reduced, thereby insuring effective starting of the compressor even when driven by an electric motor having a relatively low starting torque.  As soon as the compressor resumes operation, the pressure in the evaporator is substantially reduced to a level well below that in the reservoir and the liquid refrig-erant in the reservoir partially vaporizes and all the refrig-erant in the reservoir, both gas and liquid, is returned promptly to the refrigerating system, insuring effective nor-mal operation of the refrigerating system.

The light trans-mitting or receiving elements may comprise optical fibers, light emitting diodes, photodetectors or the like.  A dielectric coating or stop is provided on the fiber coating or on the electrodes so as to prevent electrical contact.      A plurality of such optical fiber switches can be provided on a planar optical switch board for optical test terminations in an optical fiber communications system (FIG.1).

Abstract: Abstract of the Disclosure In a skinning machine, intended primarily for deskinning poultry pieces, a cylindrical feed screw in a cylindrical passage forms an annular feed passage between them.  The passage increases in flow capacity from a hopper at its entrance, where the pieces are received, to a skin removal station, and then decreases in flow capacity to its end. Skin removal means includes pairs of rollers mounted around the passage at the skin removal station to constitute part of the passage wall, each roller having a radially protruding rib that extends into the neighbourhood of the surface of the other roller so as to grip the skin between them and strip it from the pieces.  The rollers have a peripheral speed greater than the feed screw and part of the separated skin is passed between them out of a respective first exit.  The machine includes a cylindrical knife edge barrier at the exit from the skin removal station that engages the pieces moving axially toward the piece exit and presses them back into contact with the skin removal rollers before they leave the station.  A second exit for the majority of the skin is formed by a gap between this barrier and the skin removal means.          A gear train is provided to drive the slower rotating feed screw and the faster rotating skin removal rollers from the same motor.
